To all whom it 771//1/,7/ cm1/cern:

Beit known thatI, JAMES P. HALL, a citizen of the United States,residing' at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in MoldingMachines or Apparatus; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to numeralsof reference marked thereon, Which form a part of this specification.

This invention has reference generally to improvements in moldingmachines or apparatus; and the invention relates more particularly to anovel molding machine or apparatus used for the purpose of moldingconcrete blocks or bricks made from a mixture of cement and sand, butwhich may be employed for various other purposes Where a moldingmachinecan be put to practical use.

The principal object of the presentinvention is to provide a moldingmachine or apparatus of the character hereinafter set forth which shallbe of a very simple construction and is easily manipulated to produce inrapid succession agreat many bricks or the like at a great reduction oftime and expense in the manufacture of the brick and at the same timeproducing a great labor-saver, as far as making and handling the brickis concerned, and accomplishing the same amount of work in less timethan heretofore.

Ctherobjects of my present invention not at this time more particularlymentioned will be obvious from the following specification.

With the various objects of my invention in view the same consists inthe novel molding machine or apparatus hereinafter more fully set forth;and, furthermore, this invention consists in the novel arrangements andcombinations of devices and various mechanisms comprising the moldingmachine or apparatus, as well as in the details of the construction ofthe parts thereof, all of which will vbe fully described in thefollowing specification and then finally embodied in the clauses of theclaim which is appended to and which forms an essential part ofthe saidspecification.

The invention is clearly illustrated in the accompanying drawings, inWhich- Figure 1 is a front elevation of a molding machine or apparatusembodying the principles of the present invention; and Fig. 2 is atransverse vertical section of the same, thel said section being takenon line 2 2 in Fig. 1 of the drawings looking in the direction of thearrow a'. Fig. 3 is a top or plan view of the same, and Fig. 4 is acentral longitudinal vertical section showing a mixture of cement andsand molding in the shapes of bricks in a reciprocatory molding-frame ofthe apparatus. Fig. 5 is a similar sectional representation of themolding machine or apparatus, showing the reciprocatory molding-frame inits lowered position with the molded bricks removed from its moldingpockets or compartments. Fig. 6 is a longitudinal vertical section oftheupper portion of a molding machine or apparatus, a support thereon, andshowing a modified means for retaining the reciprocatory molding-framein its normally raised position. Fig. 7 is a detail vertical sectiontaken on line 7 7 in said Fig. 3, said section being made on an enlargedscale. Fig. 8 is a detail vertical sectional representation, on anenlarged scale, of one of the pallet-supporting blocks, showing` onemeans of securing such pallet-supporting blocks upon an auxiliarysupport of the table; and Fig. 9 is a sectional representation ofanother form of pallet-supporting block and means for securing it inposition.

Similar characters of reference are employed in the above-describedviews to indicate corresponding parts.

Referring now to the said drawings. the reference character 1 indicatesthe complete molding machineor apparatus, the same comprising a suitablesupporting-frame or standards 2 and a bed or table 3, having the upperconnecting-pieces f1 and tie-bolts 5. substantially as illustrated inthe several figures of the drawings. The said parts of the framework andtable or bed of the apparatus are preferably made of wood; but othermaterial. such as metal, may be employed, and the shape and generalconfiguration of the machine and the manner of connecting the parts maybe departed from, if desired. Suitably arranged upon the upper surfaceof the said bed or table 3 is an auxiliary support, which is providedalong one of its marginal edges with a chamfered portion 7, as clearlyillustrated in Fig. 3 of the drawings, and. which forms a dischargingduct or passage-way to an inclined chute 8, suitably secured upon thefront of the framework of the machine and having its inclined bottom9leading, preferably, to one of the ends of the machine. The purpose ofthe said inclined or chamfered portion 7 is that the excess of sand,cement, and

the like may be readily dusted or swept from the said chamfereddischarging edge of the auxiliary support 6 into the said chute 8 anddown its inclined bottom 9 to one side of the machine or apparatus, aswill be clearly understood. Suitably disposed upon the upper surface ofthe said auxiliary su pport 6. are any desired number ofpalletsupporting blocks 10, arranged, as will be seen from an inspectionof the several figures of the drawings, with the spaces 11 between them.The blocks 10, as indicated in Fig. 8 of the drawings, may be made ofwood, in which case they are secured in their respective positions uponthe auxiliary support 6 by means of ordinary wood -screws 12, as shown;but in place of these blocks 10 of wood I may use pallet-supportingblocks or supports 13 of metal, as indicated in Fig. 9 of the drawings,these supports for lightness in weight and cheapness of constructionbeing cast hollow and being secured to the auxiliary support 6 by meansof bolts 14 and nuts 15, as shown. A moldingframe 16 is arranged in itsnormal initial position above the upper or supporting surfaces of thesaid pallet-supports, with the upper portions of said pallet-supportspreferably extending' slightly into the molding-compartments of theframe 16, as will hereinafter appear. rhe saidA molding-frame 16 iscapable of a downward movement over the said pallet-supports in themanner to be presently described and as clearly indicated in Fig. 5 ofthe drawings. The said molding-frame 16, as will be seen from aninspection of the several figures of the drawings, consists,essentially, of a suitable frame formed with the side pieces 17 and theend pieces 18, suitably-disposed partitions 19 beingarranged between thesaid side pieces 17, as shown, and forming with the said sides 17 andends 18 suitable forming compartments or openings for the reception ofsuitable pallets 19, adapted to be arranged upon the upper surface ofeach pallet-supporting block in thc manner clearly illustrated. Thuswhen the molding-frame 16 is in its raised position (indicated in Figs.1, 2, and 4 of the drawings) the said pallets 19',

which may be made of wood, metal, glass, or

other suitable material, form, with the surrounding portions of theframe 16, suitable molds, one above each pallet-supporting block, inwhich the material for producing a brick or the like can be arranged andis tamped in position. The downward movement of the said molding-frame16 is produced by means of a suitable foot-treadle 20, to which may beattached a flexible connection 21 and a weight 22, said connection 21being passed over a suitable sheave or grooved wheel 23 for returningthe trcadle to its nornially raised position when the foot has beenremoved therefrom. The said molding-frame 16 is` connected with thefoot-treadle 2O in any suitable manner, but preferably by means of theframework shown in the drawings, which consists, essentially,`of fourguide-rods 24, suitably secured at their ends to the end portions of theside pieces 17 of the frame 16 and said guide-rodsr extending into andbeing movably arranged in correspondinglyplaced guidesextending throughthe bed ortable 3 and the support 6 thereon. At their lower end portionseach pair of said guiderods 24 are rigidly connected by a rod or bar 25,and pivotally attached to the lower ends 26 of each pair of guide-rods24 are links 27, which in turn are pivotally attached at their lowerends, as at 28, to a cross-bar 29, substantially as shown. A link 30 isconnected at its upper end with this rod 29, said link being pivotallyattached at its 'lower end portion by means of a pin 31 to thefoot-treadle 20. The guides in which the said guide-rods 24 are movablyarranged and which are for the purpose of producing a true verticalreciprocatory movement of the said moldingframe 16 consist, essentially,of screw-threaded pipe-sockets 32 and 33 and a connectingpipe 34,provided with an external screwthread screwed in the sockets 32 and 33,which are respectively secured upon the upper face of the support 6 andagainst the under surface of the bed or table 3 and are in alinementwith the oppositely-placed openings in the said parts, as will beclearly understood from an inspection of Figs. 2 and 7 of the drawings.That the said forming or molding frame 16 may be rigidly supported inits relatively raised position above the palletsupporting blocks whiletamping the material into the forms produced above the said blocks Ihave arranged upon the said support 6, at each end thereof, a slide'3,each slide being capable of being moved beneath the end piece 18 of theframe 16, as shown in Figs. 3 and 4 of the drawings, and thus serving assupports upon which the said frame rests while the material to be moldedor shaped is being' tamped. The said slides 35 may be moved in oppositeoutward directions away from the said end pieces 18 of the frame 16 whenit is desired to lower said frame by means of a shaft or spindle 36,provided at its end portions, respectively, with right and left screwportions 37 and 38, upon which are movably arranged correspondingly-formed screw collars or nuts 39 and 40. The said shaft or spindle 36can be turned in either direction by means of a crank 41, and extendingin an upward direction from each screw collar or nut on said shaft orspindle is a post or bar 42, movably arranged in the open or cut-awayportions 43 and 44 of the bed or table 3 and the said auxiliary support6, respectively, and suitably secured to the respective slides 35. Itwill thus be evident that by turning the said shaft or spindle 36 thesaid slides can be moved simultaneously in opposite directions eitheroutwardly or inwardly, according to the direction of rotation of thesaid shaft or spindle, to enable the frame 16 to be lowered or to enablethe said slides to act as supports when the said frame 16 is in itsraised position. The said shaft or spindle 36 is rotatably arranged insuitable bearings 45, secured upon the under side of the bed or table 3,the shaft or spindle being provided with suitable collars or otherenlargements, as 46, or other means to prevent any lateral displacementof the shaft. In lieu of this mechanism for producing the reciprocatorymovements of the said slides 35 a modified means (represented in Fig. 6of the drawings) may be employed. With this form of mechanism the bed ortable 3 is provided with a longitudinally-extending opening 47, and inthe support 6 is a correspondingly-arranged opening 48. A shaft orspindle 49 extends laterally beneath the said bed or table 3, the saidshaft or spindle 49 being turned by means of a crank 50. The said shaftor spindle 49 is provided with a disk or crank 51, and pivotallyconnected with the said disk or crank are a pair of connecting rods orlinks 52, which extend upwardly and in opposite directions through theopenings 47 and 48 and are respectively pivotally connected, as at 53,with the respective slides 35, substantially in the manner illustrated.The operations of this mechanism for sliding the slides 35 in theiropposite outward or inward directions will be clearly understood from aninspection of said Fig. 6 of the drawings.

The manner of operating the machine or apparatus 1 after the materialhas been molded or formed upon the pallets 19 as illustrated in Fig. 4briefly is as follows: The material having been suiiciently tamped toprovide the bricks or molded blocks, the slides 35 are moved oppositelyin their outward directions to bring the said slides in the positionsindicated in Fig. 5 of the drawings. The operator then applies pressureupon the foot-treadle 2O to thereby bring the frame 16 from itspreviously-raised position (indicated in Figs. 1, 2 and 4) to itslowered position. (Shown in Fig. 5 of the drawings.) Still retaining thefoot upon the treadle, the bricks or molded blocks resting upon thepallets 19', which have been removed with the said bricks or blocks fromthe forming-compartments of the moldingframe.16 and remain upon thesupportingblocks 10, are then by means of a board or other suitabledevice pushed upon a pallet or board 55, resting upon a block or/support54, as represented in Figs. 2 and 3 of the drawings, thence to becarried away for drying and curing in the usual manner. The pressure isnow removed from the treadle and the frame 16 allowed to resume itsnormally raised relation with the pallet-supporting blocks, the slides35 being returned to their supporting positions beneath the end pieces18 of the frame 16 in the manner above stated and the pallets 19' thenbeing replaced upon the supportingblocks 10.

From the foregoing description of my invention it will be clearly seenthat I have devised a simply-constructed and efciently- Working moldingmachine or apparatus in which bricks and other bodies can be rapidlyformed in large quantities.

Of course I am aware that changes may be made in the arrangements andcombinations ofthe various devices and mechanisms for producing thereciprocatory movements of a molding-frame no matter whether the formingis done upon pallets placed upon palletsupporting blocks or otherwise,and -I am aware also that changes may be made in the details of theconstruction of. the various parts of the machine without departing fromthe scope of my present invention. Hence I do not limit my invention tothe exact arrangements and combinations of the devices and mechanisms,nor to the parts thereof as described in the foregoing specification andas illustrated in the accompanyingdrawings, nor do I confine myself tothe exact details of the construction of the said parts.
